UNSPSC 51283951: Sulfamethoxazole sodium

This classification denotes a sulfonamide anti-infective agent C10H10N3O3S.Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier PJ0X8H59AI, chemically known as benzenesulfonamide, 4-amino-n-(5-methyl-3-isoxazolyl)-, sodium salt (1:1), but more generally known as sulfamethoxazole sodium, which bears US NIH Compound Identifier 5329. European Medicines Agency schedules Sulfamethoxazole sodium in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB35068.

Most nations, for tariff and trade purposes, schedule sulfamethoxazole sodium under HS 29350090 and SITC 51580. As of Q4 2014, SULFAMETHOXAZOLE SODIUM remains US FDA's Preferred Term for this commodity. SMILES: CC1CC(NO1)[N-]S(=O)(=O)C2CCC(CC2)N.[NA+].

UNSPSC 51283951 Sulfamethoxazole sodium is a Commodity code that represents a single pharmaceutical product line, yet the recent state and local opportunities posted under this code show minimal direct alignment with the code's nominal scope. The Illinois Department of Public Health's August 2026 piggyback pharmaceutical warehouse contract through MMCAP Infuse awarded to Chartwell Rx LLC covers Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets—neither of which is sulfamethoxazole sodium—with a total contract value of $2,999,999.11 over three years. Seminole County, Florida's June 2026 procurement for 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually similarly diverges from the code's substance-specific classification. State and local health departments and county governments are the primary issuing bodies soliciting pharmaceutical products under this code tier, but the actual products purchased differ substantially from sulfamethoxazole sodium itself.

The recent opportunities show activity in Illinois and Florida, with the Seminole County solicitation issued as an IFB on June 30, 2026, with a response deadline of July 26, 2026, requiring quarterly deliveries to Sanford, Florida and vendor-covered shipping costs. The code exhibits little relevant recent activity directly tied to sulfamethoxazole sodium procurement; the opportunities tagged to it reflect broader pharmaceutical supply and emergency medical countermeasure categories rather than this specific antibiotic formulation. Vendors considering pursuit under this code should verify the actual substance or product class in each issued RFP or IFB, as tagging inconsistencies between the UNSPSC classification and the work being solicited appear common in state and local pharmaceutical procurement.
